You seem to be one of the more knowledgable people on here. Could you take a look at this thread and tell me what you think. I am running out of ideas. I am not throwing any codes. The truck did sit for a long time.

Hi Sean, maybe you can help me here, thanks for responding to my thread btw... What is the procedure for getting this ujoint out while the drive shaft is in place? I know how to do it with the drive shaft removed...

Sean I saw one of your posts that said that there was a fusible link for the FP relay to the starter solenoid. A yellow wire. My question is do you mean on the starter or on the starter relay. as some people call it the solenoid. I think I may have shorted mine out . it's a 90 5.0 4x4 I was messing with the FP relay AND GROUNDED IT. Looked like sparks flew out of or around the battery. any help would be appreciated. you seem to be very knowledgeable

actually no.. i just ran koeo again and it did 111 then waited and flashed one time then started doing other codes. 157,158,332,334,452. just put k&n intake on it and 157 and 158 have to do with MAF. what could have caused this?
